Possible Causes

Inconsistent pellet feed due to auger binding, Excessive ash buildup in firepot, Weak combustion fan airflow, Poor quality or damp pellets

How to Fix / Troubleshooting

Safety first: Allow the grill to cool and ensure there are no active embers before cleaning.

  • Step 1 – Deep clean firepot: Remove grates and drip tray. Vacuum the firepot and surrounding cavity thoroughly.
  • Step 2 – Inspect pellets: Empty the hopper and discard any damp or crumbly pellets. Refill with fresh, dry pellets.
  • Step 3 – Check auger feed pattern: With an empty firepot, run the grill on SMOKE or low and observe pellet drops. They should be regular and consistent. If feed is erratic, inspect the auger for partial jams.
  • Step 4 – Verify fan performance: Listen for steady fan operation. If the fan surges or stops, troubleshoot the fan motor and wiring.
  • Step 5 – Wind management: Avoid strong crosswinds directly into the exhaust or air inlets, which can blow out the flame.
